A cache memory testing method is employed to test a cache memory control mechanism which controls data coherency between cache memories or between a main storage unit and a cache memory in a system including N processors each having a cache memory and coupled to the main storage unit, where the processors are access sources and N is an integer greater than one. The cache memory testing method includes the steps of (a) dividing a control unit depending on N, and allocating access regions within the cache memories at positions which are mutually different and are peculiar to each of the N processors in the divided portions of the control unit, where the control unit is a mechanical minimum unit of the data coherency control, and (b) testing the cache memory control mechanism based on read data by writing data to and reading data from only the peculiar access regions within the same control unit by each of the N processors.

Cache memory testing method

A container substantially made of plastic materials and having a gas barrier property. The container has a wall including a laminated sheet which comprises an inner layer and an outer layer both made of a thermoplastic material and an intermediate barrier layer between the inner and outer layers and made of a resin material of which gas barrier property can be improved by stretching. The intermediate layer is held between the inner and outer layers in a stretched state. A rigid layer of a large thickness may be provided outside the outer layer. In manufacturing the container, the intermediate layer may be in a stretched state when the laminate is provided. The rate of stretching can be increased when the laminated sheet is formed into the shape of the container.

Plastic container and method for manufacturing the same

A container lid structure made essentially of plastics. The lid structure includes a lid frame and a lid plate. The lid plate includes an inner layer comprising a metal foil coated at the opposite sides by plastic layers and connected at the peripheral portion with the lid frame and a core made of a material which is not adhesive to or has a weak bonding power with the plastic material for the lid frame and for the plastic layer of the inner layer. The core is laid over the inner layer with the peripheral portion in an abutting relationship with the inner periphery of the lid frame. A holding member is formed on the core and bonded to the inner layer through apertures in the core. A pulling tab is also formed on the core and bonded to the inner layer through an aperture in the core.
